Abstract

To realize charging while in non-contact processing operation for the purpose other than charging. An approach of a portable electronic device 2 with a rapid bulk electricity storing module 20, which is a chargeable power source, is detected at the side of a power transmitting device 1, and power transmission for charging the rapid bulk electricity storing module 20 is executed in response to the detection of the approach. A power source can be charged in operation for non-contact authentication which is executed when a device approaches an authentication device.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a power transmitting device, a power receiving device, an authentication / billing proxy device, an electrical charging system and an electrical charging method, more specifically to a power transmitting device, a power receiving device, an authentication / billing proxy device, an electrical charging system, a power transmitting method, a power receiving method and an electrical charging method which are used in charging a battery provided for a portable electronic device such as a cellular phone, a notebook PC (Personal Computer) and a PDA (Personal Digital Assistant). [0003] 2. Description of the Related Art [0004] Non-contact power transmitting techniques, non-contact processing techniques and high-speedbulk electricity storage techniques have been known. For example, as a non-contact power transmitting technique, a non-contact power transmitting module is known (for example, see “th...

AI Technical Summary

Benefits of technology

[0013] By adapting a power transmitting device like that, charging of a power receiving device can be realized while in non-contact processing operation for the purpose other than charging such as authentication or making a payment. By using a non-contact power transmitting technique and a high-speed bulk electricity storage technique, charging can be rapidly executed bit by bit in a short time of a non-contact processing operation about one to three seconds. That can reduce a load to a user to be attentive to charging.

[0036] The abovementioned systems can provide an environment for a user to use a portable electronic device more natural and suitable to living with fewer loads to the user to be attentive to charging the device. By using the authentication / billing proxy device, the present invention enables a new business such as electric sales by the third party to be developed without increasing a load of bill to a user.

Problems solved by technology

Although Patent Document 1 discloses a basic authenticated electrical charging method and billing method, a charging time cannot be reserved enough in non-contact processing operation time for the purpose other than charging as charging starts after authentication at a server which is at a remote site with much load so that communication and processing take much time.
